利用煤泥与造纸黑液制备水煤浆的试验研究

洗煤厂排放的煤泥由于其粒度细且均一(小于75μm粒度占90%以上)、灰分含量高、含水量大、燃烧热值低等特性,如不经适当处理,难以有效利用。煤泥与黑液共制水煤浆是依托水煤浆技术开发的一种新型燃料,它既利用了洗煤厂难以有效利用的煤泥,又解决了造纸厂排放黑液的污染问题,其经济、环保、社会效益显著。笔者就它的成浆特性进行分析研究。 Slime of the coal preparation plant is characteristic of small and uniform size,high ash and water content,low calorific value. It is difficult to be availably utilized without appropriate treatment. The CWM prepared with slime and black liquor is a new type fuel,it not only makes use of the slime of the coal preparation plant but also solves the pollution problem about papermaking black liquor. Therefore,it is remarkable on its economic,environmental and society benefits. This paper introduces its' slurryability
